SANTA ROSA - A Sonoma County sheriff's deputy fired eight shots within 10 seconds at 13-year-old Andy Lopez Cruz, who was carrying what turned out to be a replica of an AK-47 rifle southwest of Santa Rosa Tuesday afternoon, a Santa Rosa police lieutenant said today.

In a news release, Lt. Paul Henry said an autopsy today showed seven entry wounds in Andy's body. One of the bullets that caused a fatal wound entered the right side of Andy's chest and the other fatal bullet entered the teen's right hip, Henry said.

Four rounds were recovered at the scene and three were recovered from Andy's body, Henry said. There were non-fatal wounds to his right wrist, left bicep, right forearm, right buttocks and right hip, Henry said.

"Investigators believe eight rounds were fired at the scene," Henry said. One or more of the bullets might have caused more than one entry wound, Henry said.

At a press conference Wednesday, Henry said the deputies were 20-30 feet from Andy when he was shot at the edge of field at the intersection of Moorland and West Robles avenues in unincorporated Sonoma County, now the site of a growing memorial to the eighth grade student.

Grief, indignation and demands to fire the deputies followed the shooting in the Latino neighborhood. The sheriff's office has not yet identified the deputies, who are on paid administrative leave.

There have been vigils at the memorial site at the intersection and a protest march was held Wednesday night. Another march is scheduled for noon Friday from the Santa Rosa Police Station to the sheriff's office in Santa Rosa about 2.5 miles away.

Henry said the deputies took cover behind the open doors of the patrol car when they saw a person with a rifle.

One of the deputies shouted "put the gun down," Henry said. Andy's back was toward the deputies, and he then began to turn toward the deputies when the deputy shouted, Henry said.

The rifle was in Andy's left hand and one of the deputies said that as Andy turned toward the deputies the barrel of the rifle was raising up and turning in his direction, Henry said.

The deputy behind the open passenger door was familiar with lethal power of what he believed was an AK-47 assault rifle, and he feared for his and his partner's safety and the safety of community members in the area, Henry said.

The deputy fired several rounds, striking Andy, Henry said.

The deputies approached Andy, handcuffed him and immediately began life-saving measures, Henry said. He was pronounced dead at the scene.

Andy also had a fake handgun in his waistband. The rifle did not have an orange tip on the barrel that is required on replica firearms but the handgun did, police said.

A timeline Henry provided this afternoon states that at 3:14:15 p.m. the deputies notified the dispatch center about a suspicious person in the area.

Four seconds later, the deputies called for emergency assistance from other deputies in the area, and six seconds after that the deputies notified dispatch shots have been fired, according to the timeline.

Emergency medical aid is advised to respond to the scene at 3:14:41 p.m., 26 seconds after the first report to the dispatch center.

The autopsy, conducted by Dr. Arthur Josselson of the Forensic Medical Group, was attended by the Santa Rosa Police Department and the Sonoma County District Attorney's Office, the agencies that are investigating the fatal shooting.
